Structure of Aluminum Zinc Rolled Coil

 Prepainted aluminum zinc rolled Coil For construction Roof

Description of Aluminum Zinc Rolled Coil
Aluminum zinc coils is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative. 

 

Main Feature of Aluminum Zinc Rolled Coil for Construction Roof

1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will  form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside. 
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover. 
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials. 
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.

Q:What are the common storage defects in steel coils?
Steel coils can suffer from various storage defects, including staining or discoloration, rust or corrosion, coil deformation, surface damage, edge damage, coil slippage, contamination, and coil nesting. These defects can negatively impact the appearance, quality, usability, and safety of the steel. To prevent these defects, it is essential to implement proper handling, storage, and protection measures. This involves storing the steel coils in a dry and well-ventilated area, away from moisture and chemicals. Additionally, appropriate stacking and support structures should be used to prevent deformation and bending. To avoid mishandling and transport damage, it is important to stack and handle the coils correctly. Adequate protection against impacts and contaminants should be provided to prevent surface scratches, dents, and abrasions, as well as edge damage. It is crucial to ensure that the edges of the coils are properly protected and secured during storage to maintain their usability and safety. Furthermore, to prevent coil slippage and potential harm to personnel or equipment, the steel coils should be securely stored and stacked. To avoid contamination, the coils should be kept away from substances like dirt, oil, grease, and chemicals. Regular inspections and maintenance should be conducted to identify and address any potential defects or issues promptly. Overall, by implementing these proper handling, storage, and protection measures, the occurrence of these common storage defects in steel coils can be minimized, ensuring the appearance, quality, usability, and safety of the steel.
Q:I mean 4 inch thick steel like was used in the WTC buildings, especially WTC 7 which did not get hit by a plane. Can carpeting, desk chairs, water coolers and dry erase boards burn hot enough and long enough to melt steel that is normally made in a blast furnace?
Steel loses strength as it is heated and will fail long before it melts. A mild steel that starts out at 100 degs F with an allowable stress level of 20,000 psi will be down to only about 2000 psi at 1000 degrees. As to fireproofing for steel. It doesn't have an unlimited life. In fact most has only a 2 to 4 hour rating and that is determined in ideal conditions in a laboratory. The idea is to give firefighters time to get everyone out of the buidling.
Q:How are steel coils used in the production of agricultural irrigation systems?
Steel coils are used in the production of agricultural irrigation systems to create the pipes and tubing that transport water to crops. These coils are formed into various designs to meet specific irrigation needs, ensuring efficient and reliable water distribution for optimal crop growth.

Q:We are going to build a house with a steel frame.Someone told me today that these houses have problems with humidity.Is that true?Please tell me all you know..
the building I work in is steel framed, no humidity problems. I can't believe that steel frame anything causes humidity problems. I would ask for an explanation from whom ever told you this. One thing is cell phones, radios etc. have bad reception due to all the interference.
Q:Went to top gun range in Houston, Tx. Guy there said no steel bullets..Anyone know why? Think i can shoot them anywhere else? Perhaps an outdoor gun range? The are monarch FMJ 9mm steel rounds..Thanks!
Indoor ranges and ranges that provide steel targets don't like them because of the additional wear and tear on their equipment. Some outdoor ranges don't allow them because they can strike sparks when they hit rocks and cause a fire. Others don't care. Best to call ahead or check the range's web site, if any, to see what they allow and don't allow.
